연합인증

연합인증 가입 기관의 연구자들은 소속기관의 인증정보(ID와 암호)를 이용해 다른 대학, 연구기관, 서비스 공급자의 다양한 온라인 자원과 연구 데이터를 이용할 수 있습니다.

이는 여행자가 자국에서 발행 받은 여권으로 세계 각국을 자유롭게 여행할 수 있는 것과 같습니다.

연합인증으로 이용이 가능한 서비스는 NTIS, DataON, Edison, Kafe, Webinar 등이 있습니다.

한번의 인증절차만으로 연합인증 가입 서비스에 추가 로그인 없이 이용이 가능합니다.

다만, 연합인증을 위해서는 최초 1회만 인증 절차가 필요합니다. (회원이 아닐 경우 회원 가입이 필요합니다.)

연합인증 절차는 다음과 같습니다.

최초이용시에는
ScienceON에 로그인 → 연합인증 서비스 접속 → 로그인 (본인 확인 또는 회원가입) → 서비스 이용

그 이후에는
ScienceON 로그인 → 연합인증 서비스 접속 → 서비스 이용

연합인증을 활용하시면 KISTI가 제공하는 다양한 서비스를 편리하게 이용하실 수 있습니다.

A vacuum container for preserving food is disclosed herein that includes a cover member for covering an upper part of a container member in which food is filled, a piston member equipped with the cover member and ascending and descending movable, and first and second valve members that alternately operate by a pumping operation using ascending and descending operation of the piston member to make a suction aperture and an exhaust aperture alternately open and close, thus discharging air from within the container member. Such operation allows the interior of the container member to become a vacuum state, thereby allowing food within the container member to be preserved for a longer time period, in a more sanitary manner, and a simple manufacture and a low manufacturing cost to provide users with convenience.

What is claimed is: 1. A vacuum container to preserve food, comprising: a cover member for covering an upper part of a container member having a space in which food is filled, said cover member having a sliding flute downward concaved in a center thereof with a predetermined diameter, wherein a bottom face center of said sliding flute is downward concaved with a diameter smaller than an inner diameter of the sliding flute to thus form a first valve flute, a center of said first valve flute being provided as a suction aperture piercing vertically thereon, and an upper end part of said sliding flute being provided as a deviation preventing flute; a first valve member, which has numerous air holes that are formed in an outer circumference part of a plate face thereof and which is put in the first valve flute to control the suction aperture provided in a center thereof; a valve guide member mounted whose lower part has a pipe shape in which the first valve member can minutely ascending and descending move, whose upper part is provided as a guide part that is formed being upward extended in a pipe shape having an inner diameter smaller than a diameter between ends of the air holes formed in the first valve member, and whose upper part face for connecting between outer circumference faces of an upper part and a lower part of the valve guide member has a plurality of air holes with a fine diameter; a spring member of which a lower end part is mounted on an outer side of the guide part of the valve guide member, and which has a vertical elasticity; a piston member of a pipe shape opened downward, of which the interior accommodates the spring member, and of which a center of an upper face has a second valve flute downward concaved with a predetermined diameter, a center of said second valve flute having an exhaust aperture piercing vertically, and of which opposite portions of an outer circumference face are formed as rotation preventing faces of a vertically cut plane face shape, an upper end one side of said rotation preventing face being formed as a stopping flute, and of which an outer circumference part of a lower end part is provided with a stopping jaw formed being extended outward from an outer diameter, said stopping jaw being provided with a sealing unit to closely adhere with an inner circumference face of the sliding flute of the cover member; a deviation preventing member, into which an outer circumference face of the piston member is matching inserted to be attachable and detachable, and which is mounted in an upper end part of the sliding flute, and which is provided with a protrusion that is formed in one body from a lower end part extended downward from an inner circumference face thereof; a second valve member mounted in the second valve flute formed in an upper face of the piston member, to control the exhaust aperture formed in the center of the piston member; and a cap member, which has an insertion flute formed in an inner circumference face thereof, said insertion flute being insertion combined with a protrusion that is formed being projected outward from an upper end part of an outer circumference face of the piston member, and which is provided with an exhaust flute that is formed by a radial type in a ceiling face and an inner circumference face thereof. 2. The container of claim 1, wherein the cover member is provided with an air inlet formed in one side of the sliding hole, where said air inlet is equipped with a valve body on which a spring is wound from an upper part to an outer circumference face thereof, an upper end part of said valve body being formed larger than a diameter of the air inlet of the cover member, and a lower end part of said valve body being partially projected from a lower part of the cover member to be screw combined with a spring supporter and thus prevent the spring from deviating from the valve body, where said valve body is provided with a sealing unit that is equipped between a lower face of a head part of the valve body and its opposite cover member, and said head part of said valve body is provided with a vacuum removal member that is provided with a loop of a ring shape into which at least one finger can be inserted. 3. The container of claim 1, wherein the cover member is provided with an air leading flute formed being downward concaved at one side of the cover member, a lower end part of said air leading flute being provided as an air inflow hole piercing vertically, and the interior of said air leading flute being provided with a guide of a pipe shape whose flange face is stuck and solidly fixed to the cover member, where said guide is insertion combined with an elevating shaft elastically supported by the spring to be ascending and descending movable, an upper end part of said elevating shaft positioned in an upper side of the guide having an outer diameter larger than an outer diameter of the guide, and a lower end part of said elevating shaft projected through a lower side of the guide having a stopping jaw; where an upper part of said stopping jaw is covered with a packing, an upper part of said packing is axis combined with the spring supporter, an inner circumference face of said guide is minutely extended toward an inner side to thus form a spring support jaw so that the spring can be combined between the spring support jaw and the spring supporter supported by the packing. 4. The container of claim 1, wherein the deviation preventing member displays a month and a day for indicating a preserving start time of food in an outer circumference part thereof, an ending part of said outer circumference part being provided with one pair of pointers that is movable along an outer circumference face thereof and that indicates a preserving start month and date of the food.
